To all whom it may concern:

Be it known that I, EDWARD F. POLAND, a citizen of the United States,residing at Boston, in the county ofSuli'olk and State ofvMassachusetts, have invented an Improvement in Hydro-Extractors, ofwhich the following is a specification.

This invention relates to hydro-extractors having a belt-drive, and hasfor its object to provide the receptacle containing the basket with aclosing-lid, and with means connected with said lid and adapted to en- 4gage or interlock with the belt-pulley when the belt-pulley is at restbut not to engage therewith when the belt-pulley is revolving,

. said means controlling the opening of the lid, whereby the lidv can beopened only when the machine is at rest, and said means being also soconstructed and arranged as to require the closing of the lid before themachine is started.

The invention involves essentially a trig adapted to be moved into anyof the openings between the spokes of the belt-pulley, or it may be anopening especially provided in the belt-pulley, and when thus engagingsaid pulley the machine cannot be started until the trig is moved out ofengagement therewith; and said trig is yieldingly supported so that incase it should be moved into engagement with the pulley while the pulleyis revolving the spokes of the pulley will strike the end of the trigand repeatedly move it backward, and produce a loud noise, thereby tonotify the operator that the machine has not yet come to rest. Said trigis connected by suitable mechanism with the closing-lid so as to bemoved in one direction upon opening said lid and in the other directionupon closing it.

My invention is applicable to any of the well-known forms ofhydro-extractors having belt-pulleys at the base of the machine or atthe top, or elsewhere disposed, the mechanism connecting the trig withthe closing-lid being changed to accommodate the position of thebelt-pulley.

Figure 1 is a front elevatlon of a hydroextractor embodying thisinvention having a closing-lid and means for controlling its movement.Fig. 2 is a right. hand side elevation of the hydro-extractor shown inFig. 1. Fig. 3 is a fragmentary view of the closing-lid and connectingmeans. Fig. 4 is a horizontal section on the dotted line .fr-:v Fig. 1.Figs. 5 land 6 are views of modifications of basket 12;'13 and theinvention applied to other forms of hydro-extractors than that shown inFig. 1.

Referring to Figs. 1 to 4 wherein one type of hydro-extractor withbelt-drive is shown, 10 represents the receptacle containing the' 14belt-pulleys over which which also passes around a belt-pulley 15 on theupright shaft of the basket. 18 is a closing-lid for the receptacle 10,and, as here shown, said lid is connected with the receptacle by a hinge19, of any suitable construction, 20 representing the pintle orpivot-pin of the hinge. Said closing-lid'has a handle 22 by which it maybe moved up and-down as occasion may require, thereby to open and closethe opening at the top of the receptacle. As represented in saidfigures, a link 25 is loosely connected at one end to an ear 26 at thetop of the hinge, or it may be elsewhere loosely connected with theclosing-lid, the other end of said link being loosely connected with ashort arm 28 arranged at the upper end of an upright rod 29, said armbeing arranged at right angles to said rod or thereabout, whereby uponlongitudinal movement of the link said arm'will be swung in a substanabelt passes,

tially horizontal plane and said rod will becorrespondingly oscillated.Said link is disposed between a pair of ears 30 arranged at the top ofthe receptacle by which itis held against lateral movement; and saidoscillating rod has suitable bearings on the side of the receptacle. Tothe lower endportion of said rod a short arm 32 is secured, which isextended from the rod at an angle and is swung back and forth in asubstantially horizontal plane by the oscillating rod. Said short arm 32occupies a position between a pair of pins 35, projecting upward from abar 36, which is slidably supported in end-bearings provided for it.Said bar is arranged adjacent one of the belt-pulleys, as 13 forinstance, and one of its end-portions is movable into and out ofengagement with said pulley, as for instance, said endportion is movableinto and out of any of the openings between the spokes of said pulley orany opening which may be purposely rovided for it in the pulley. Saidslidingar serves as a trig for the beltpulley, as when in engagementtherewith said belt-pulley is held at rest. By the connecting-means hereshown between the closing-lid and the trig it will be seen that as thelid is raised the link 25 will be moved longitudinally and the rod 29will be oscillated and the trig will be moved into engagement with thebelt-pulley, and as the closing-lid is lowered said trig will be movedlin the opposite direction for disengagement from the belt-pulley. Whenthe trig is in engagement with the belt-pulley the closing-lid is heldopen and the machine cannot be started for the reason that the trigholds the belt-pulley at rest. When it is desired to start the machinethe closing-lid must be closed, and thereupon the trig is moved ont ofengagement with the belt-pulley and the belt-pulley is then free torotate. While the belt-pulley is rotating should an attempt be made toopen the closing-lid it will be lseen that the trig will be moved intoengagement with said pulley and the spokes thereof will repeatedlyengage the end-portion of the trig and will repeatedly move said trigbackward, making a loud noise, and thus calling the attention of theoperator to the fact that the belt-pulley is rotating and the machine isstill running.

Referring to Fig. 5, wherein another type of hydro-extract or withbelt-drive is shown, the belt-pulley is arranged at the top of themachine and the closing-lid 18 is connec-ted with the receptacle in thesame manner as ypreviously described, and a link is loosely connected toan ear on the hinge of 'the closing-lid, which loosely engages annpright pin 5G, rising from a sliding-bar 57 or trig which is arrangedin suitable bearings at the top of the receptacle adjacent thebeltpulley 50, said bar being movable into and out of engagement withsaid belt-pulley in substantially thc same manner as heretoforedescribed, by sliding it in opposite bearings.

Referring to Fig. G another form of hydroi extract or with belt-drive isshown having a belt-pulley G0 arranged at the top of the machine, and inthis instance a slidably supported trig G5 is employed which is engagedby one arm (3G or' a bell-crank lever, the

other arm 67 of said lever being loosely conl nec-ted by a link (3S withan ear on the closinglid 1 8. These several forms of hydro-extractorsare shown as illustrating some of. those to which my invention isapplicable, and I desire it to be understood that other forms may be emloyed in lieu of those here shown; and furt iermore, that other forms ofconnecting-means between the trig and closing-lid may be employed, andalso trigs of other forms, without departing from the spirit and scopeof my invention.

I claim 1'. In a hydro-extractor having a beltdrive, a pivotallysupported closing-lid for the receptacle containing the basket, a trigslidably supported for engafrement with and disengagement from thebelt-pulley, and means connecting said trig with the closinglid wherebythe trig is slid upon movement of the lid, substantially as described.

2. In ahydro-extractor having abeltedrive, pivotally supported.closing-lid for the receptacle containing the basket, a bar slidablysupported at the side of the belt-pulley and movable intoI and out of anopening in said pulley, and means connecting said bar with theclosing-lid whereby it is moved longitudinally upon movement of saidlid, substantially as described.

3. Ina hydro-extractor havingabclt-drive, aclosing-lid for thereceptacle containing the basket, pivotally supported thereon andarranged for movement upand down, a link loosely connected with said lidand movable longitudinally upon movementV thereof, an upright rodadapted for oscillation, having a short arm at its upper end which isloosely connected with said link and having a short arm at its lowerend, and a slidably supported trig arranged adjacent thebelt-pulley andadapted to engage and disengage said pulley, said trighaving means foroperatively connecting it with said last-named short arm, substantiallyas described.

In testimony whereof, I have signed my name to this specication, in thepresence of two subscribing witnesses.

EDWARD F. POLAND.
